vSLING-LOCK TRIP.

SPECIFICATION forming part of Letters Patent No. 690,659, dated January7, 1902.

. Application filed September 14, 1901. Serial No. AM. (No model.)

To all 1.0700727, it may concern:

Be it known that I, JACOB NEY, a citizen of the United States, residingat Canton, in the county of Stark and State of Ohio, have invent-edcertain new and useful Improvements in Sling- Lock Trips; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being-had to the annexed d rawings,making a part of this specification, and to the figures of referencemarked thereon, in which.

Figure 1 is a view showing the body or casing and the trip-head detachedtherefrom. Fig. 2 is a view showing portions of a sling and thetrip-head in position to lock the ends of the sling together. Fig. 3 isa view showing the difierent parts of the trip and illustrating theparts in position to lock the head. Fig. 4 is a view showing thedifferent parts of the trip and illustrating the position of the partsbefore the head is locked. Fig. 5 is a view showing the body andillustrating the movable parts removed. Fig. 6 is a detached view of thepull or trip bar. Fig. 7 is a detached View of the 'trip-headlocking-dog. Fig. 8 is a detached view of the dog-locking pawl.

The present invention has relation to slinglock trips; and it consistsin the different parts and combination of parts hereinafter described,and particularly pointed out in the claims.

Similar numerals of reference indicate correspondingparts in all thefigures of the drawings. r

In the accompanying drawings, 1 represents the case or housing, which ispreferably of the form shown, and to which case or housing is attachedin any convenient and wellknown manner the cover or plate 2, which coveror plate is for the purpose of properly inclosing the Working parts ofthe look. For

the purpose of providing a means for con necting one end or section ofthe sling proper the body or casing 1 is provided with the eyes 3, whichare located opposite each other, which are illustrated in the drawings,and are arranged so as to attach the sling-rope 4 thereto and to thebody 1.

The trip-head 5 is provided with the eyes 6, which eyes are for thepurpose of providing the body proper.

which trip-bar is provided withlthe trip-rope a means for attaching thesling-rope 7, and

when the trip-head 5 is connected to the body 1, as illustrated in Fig.2, the ends of the sling proper are locked or connected together and 1 55 remain together until the trip-head 5 is disengaged from the body 1,as hereinafter described. The trip-head 5 is provided with the enlargedrounded end 8, which enlarged rounded end is passed into the opening 9,formed in the end of the casing 1.- Opposite the opening 8 is locatedthe dog 9, which dog is preferably connected to the casing by means ofthe lugs 10, which lugs arelocated upon opposite sides of the dog andare journaled in the casing 1 and the cover 2.' The dog 9 is providedwith the hooked end 11, which hooked end comes under the head 8, asillustrated in Fig. 3, and locks the trip-head 5 to To the casing 1 andthe cover 2 is pivotally connected the pawl 12, which pawl is providedwith the recess 13,which recess is for the purpose of receiving theextension 14, formed upon the dog 9, when said parts are in. the 75position illustrated in Fig. 3, and when in the position so illustratedthe ends of the sling properare locked together. To the pawl 12 ispivotally connected the pull or trip bar 15,

8o attaching-head 16, which may be of the form shown or of any otherdesired form, as the only object is to provide a means for connectingthe trip-rope 17 thereto. To one side of the pull or trip bar 15 islocated the arm 18, and around which arm is located the spring 19, oneend of said spring bearing against the plate or flange 20, which plateor flange is formed integral with the casing or held in fixed positionwith reference to the casing and cover. The opposite end of saidspringbears against the lateral flange 21, which lateral flange isformed integral with pull or trip bar 15.

In use when it is desired to connect the triphead 5 to the body 1 thehead 8ispassed into the opening 8, said head coming against the dog 9,which turnsthe dog upon its pivotal point and moves the hooked end 11under the head. As the head moves to turn the dog the extension 14: isthrown upward, moving the pawl 12 upon its pivotal points, at the sameICO time imparting an end movement to the trip or pull bar 15, and whenthe extension 14 comes in line with the recess 13 said pawl will beforced downward or toward the extension 14, so as to engage saidextension in the recess 13, and thereby lock the dog 9 in the positionillustrated in Fig. 3. It will be understood that the spring 19 willforce the trip or pull bar 15 endwise at the moment the extension 14.comes under the recess 13. When it is desired to release the ends of thesling proper, the trip-rope 7 is pulled, which imparts longitudinalmovement to the trip or pull bar 15, which in turn moves the pawl 12 soas to 'disengage its recess from the extension14, at which time the dog9 is free to turn upon its pivotal points and allow the trip-head topass the hooked end 11.

For the purpose of preventing the head 8 from becoming accidentallydetached from the dog 9 and at the same time assisting in guiding thehead 8 so as to come into proper engagement with the hooked end of thedog the flange 22 is provided, which flange is located substantially asshown in Figs. 3, 4, and 5. By pivoting the trip-bar 15 at one side ofthe locking-point of the dog an easy trip is provided owing to theincreased leverage.

Having fully described my invention what I claim as new, and desire tosecure by Letters Patent, is

1. The combination of acasing or housing, a detachable trip-headprovided with a connecting-head, a dog provided with a hooked end and anextension, a pawl pivotally connected to the casing and provided with arecess, a trip-bar pivoted to the pawland provided with an arm, and aspring located around the arm, all arranged, substantially as and forthe purpose specified.

2. In a sling-lock trip the combination of a casing provided with anopening at one end thereof, a dog located in the casing opposite theopening, a detachable trip-head provided with a connecting-head, aspring-actuated trip-rod pivotally connected to a pawl and the pawlprovided with a recess adapted to engage the extension of the dog,substantially as and for the purpose specified.

3. The combination of a casing having an opening and provided withsling-rope connecting-eyes, a detachable trip-head provided withsling-rope connecting-eyes, a spring-actuated trip-bar and means forlocking the trip-head to the casing, substantially as and for thepurpose specified.

4. The combination of a casing having an opening, a guide-flange locateduponone side of the opening, a trip-head, a dog pivotally connected tothe casing and provided with an extension, a pawl provided with arecess, a spring-actuated trip-rod pivotally connected to the pawl andmeans for connecting the sling-rope to the trip-head and to the casing,substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JACOB NEY.
